I have a new laptop "YOGA" with W11. Now I want to add an extra e-mail address. I am in Sweden and now I want to add my Spanish e-mail. It is a " @telefonica.net" address. I only want it to receive mail, to send mail I use my ordinary swedish mail. When I put in the "@telefonica.net" Thunderbird will not respond it says "use only letters and figures etc"

How can I fix this?

Ever since the latest update to Firefox nightly on Android, whenever I try to open the browser I get a pop up asking me if I want to open it with the Play Store or the Samsung store. I went ahead and updated it and it continues to do this every single time I try to open the browser. It continually opens the Play Store as well. This must be some bug as it is happening on both of my devices that I recently updated Firefox nightly, both my phone and my tablet.

Suddenly, my "main" comcast account is no longer accessible via Thunderbird. I have three accounts set up: two comcast and one gmail. The gmail and one comcast account appear to be all right. When I try to access the comcast one I call main, I receive the window shown in the uploaded image. It seems as if TB has somehow forgotten the way it accesses "main" accounts. I have verified that the "main" account is fine on the comcast server by logging into it. The question is if I remove the TB "main" account and recreate it, will I lose any messages? Is this likely to correct the issue?

I have lost the indicator in the folder pane showing which folder I'm in. It used to have a small color tab in the folder pane on the left hand side. Indicating that the folder was selected. Any ideas to get it back? Thunderbird 140.3.1esr (64-bit)

Getting a weird issue. When I open Firefox Beta, if it is not already running it loses focus on Firefox and pops open the Google Play Store over the top of Firefox on its Firefox Beta page. It's doing this consistently and repeatably. I'm on a Samsung Galaxy A52 5G on the latest update of Android 14.

I've been trying to add yahoo account for several weeks, I type in the email address on the add account function and then I just get a wheel of death and have to force shut the programme, I'm on windows 11.

Hello I deleted a lot of emails, and I am not sure if all my old emails have been completely deleted. When I go to open Thunderbird, after about a minute it will freeze up. I have 3 email accounts and I can only view one account but when I try to view another email account, it freezes up, and I have to exit. Before I deleted my emails it all worked great no problems. What did I do wrong and what can I do to get Thunderbird back to working like it use to ? Thanks a lot Sam

When new emails come in the emails are highlighted (bold type) and also there is an orange diamond shaped icon in the email entry. In addition, the email folder name font will be blue to indicate there are new emails in the folder.

Mostly this works but some emails are filtered and, although there are new emails in the folder this blue status appears to be lost. Also, the orange diamond signifying "new" is lost too.

The lack of blue folder highlight is definitely the result of the emails losing their "new" status.

It is a little inconsistent until I find a pattern. All I know is the "new" status change is the result of filtering. None of the filters has any action other than "move to...". I never mark as read or even delete them.

Is there any way of checking the email status in the SQLite database?

Hello,

I've been using Thunderbird for years with the same setup: - Windows 10 64bit - Thunderbird always running, with 4 linked mailboxes (all POP), each checking for new mail every 5 minutes - The OS is typically running for a month or longer without restarting (I always hibernate my PC instead of shutting it down)

Everything was working just fine until recently. In the past month (or two, I'm not sure) Thunderbird just stopped receiving new e-mails on 3 different occasions. No error messages or anything, I always notice only when the sender calls/texts me, asking me about an e-mail I didn't get which is very annoying. When this happens, Thunderbird seems to work normally (I can browse all the mailboxes, move e-mails between folders etc.) but it just never downloads new messages from any of the mailboxes (not even when I hit F5 or the "Get messages" button - which normally displays a brief "Host contacted, sending login information..." message in the status bar but does absolutely nothing when this problem occurs). When I spot this problem and kill Thunderbird via task manager (closing normally doesn't help because it will still run in the background) and run it again, it immediately downloads the missing e-mails on startup and resumes working normally. But I'm getting really nervous about possibly missing important message(s) because Thunderbird is my primary (and for 99 % of time, the only) way of accessing my mailboxes (I only login to the web UI when I suspect Gmail or other web hosts to false flag an e-mail from legit sender as spam - but I typically only do this couple times a year).

My Thunderbird is (always) up to date (v 140.3.1esr).

Do you have any idea how to fix this, please? TIA! 🙏

I am trying to setup Thunderbird on a new Windows 11 PC. My current PC is running Windows 10. I am thoroughly frustrated to the point where I might just switch to Outlook!

First some basic parameters.

On a "techie" skill level I am about a 3 on a scale of 10. I have been a Thurderbird user for a long time, 15+ years. The Thunderbird version on the Windows 10 PC is 140.3.1esr(32-bit) The Thurderbird version on the Windows 11 PC is 143.0.0(64-bit) I managed to stumble through a Thunderbird migration change 6 years ago when I purchased my current Windows 10 PC.

Here are the issues I am having.

1. I do not know how to locate and transfer to the new PC all of my contacts. 2. I do not know how to locate and transfer the sent mail history. 3. The Windows 11 PC version is not synchronizing with the mail server (Comcast.net). When I read, delete, or move an email it is still showing as unread on my other devices. (The Windows 10 PC, iPad, iPhone) Conversely, if I read an email on one of the other devices, it still shows as unread on the Window 11 PC. 4. The is no Junk mail showing in the Junk folder on the Windows 11 PC, but junk mail will show in the Junk folder on the Windows 10 PC. I clean the Junk folder regularly. However, the junk mail is being filter out on the Windows 11 PC because it is not showing in the Inbox. 5. (Somewhat minor) On the Windows 11 machine the preview panel is on the right. On the Windows 10 machine the preview panel on the bottom. I prefer the bottom. I don't see in settings were to change this.

What I have done so far: 1. I compared setting for setting from the old PC to the new PC. I noticed in the new Windows 11 version there is no settings called "Message Synchronizing". 2. I was able to locate the file that contained all of my local files. I copied it to the new PC and directed Thurderbird to use this file. Works fine. 3. I have read the Help instructions for "How do I find my profile", "Moving a profile", Backing up a profile", Restoring a profile backup", Method using a transfer device", and "An alternative method for manual transfer between Windows 10 and Windows 11 computers".

As state above, my skill level is about a 3. When I start dealing with hidden files I am getting beyond my skill level.

My questions are: 1. Since Thunderbird seems to be setup and running, although not how I like, is it necessary to do the transfers described in the Help articles. Would I be over writing the manual setup I have completed when I compared the setup pages from the old and new PCs? 2. Can the files name for where the contacts are store be provided so I can manually copy over? I would think this would not be a hidden file. 3. How do I get the Windows 11 version to synchronize with the Comcast mail server? If the synchronizing occurs, will I get all of the "Sent" history or is this in a file that needs to be copied. FYI, the emails I sent from the Windows 11 PC has synchronized to the Windows 10 PC. 4. What are the settings for the Junk mail. The settings on the Windows 10 PC and the Windows 11 PC are the same. 5. Last but not least, how do I get the preview pane on the bottom. :-)

Thanks, and HELP!

I have installed, uninstalled, and reinstalled Thunderbird four times - and I can NOT get any of the folders from Outlook to show up so I can drag them to my Gmail account. Suggestions??

I find that many websites don't run on firefox. Examples are virgin atlantic, holiday autos and copa airlines. I have to switch to Chrome to use them. Considering that firefox releases updates frequently this situation is surprising. Is the firefox administration aware of this issue? Is there any way to overcome this problem?
